specifications can result (for example, maximum allowable pressure loss inconsistent with product size) Classification 4.1 Strainers may be classified into three general construction categories, simplex, duplex (or multiplex), and automatic (self-cleaning), as follows: 4.1.1 Simplex—A strainer consisting of a single basket or element chamber that normally requires the flow through the unit to be shut down before cleaning 4.1.1.1 Classifications of simplex strainers based on port alignment relative to basket or element chamber are Y, T, Z, and others 4.1.2 Duplex (or Multiplex)—A strainer usually consisting of at least two basket or element chambers separated by a valve (or valving) that permits continuous flow of fluid through one chamber while the other is accessible for cleaning 4.1.3 Automatic (Self-Cleaning)—A strainer providing some means for back-flushing or cleaning of the straining element while the unit is in service It can have one or more elements and may require periodic shutdown for maintenance and inspection Materials and Manufacture 6.1 Strainer housings, as well as any pressure-retaining parts, including bolting used for pressure retention, shall be constructed of materials listed in Section VIII, Division of the ASME Boiler and Pressure Vessel Code (hereafter called ASME Code) or ANSI/ASME B31.1 Bolts, screws, and fasteners in contact with interior fluid shall be of appropriate corrosion-resistant material 6.2 The pressure ratings established under this specification are based on materials of high quality produced under regular control of chemical and mechanical properties by a recognized process The manufacturer shall be prepared to submit a certificate of compliance verifying that his product has been so produced and that it has been manufactured from material whose chemical and mechanical properties are at least equal to the requirements of the appropriate standard or specification 4.2 Strainers may be further classified by pressure ratings and types of port connections, port alignments relative to unit center lines, cover closures, valve types (in duplex), types of baskets or elements, materials of construction, and other features of design 6.3 For materials not having values of allowable stress tabulated in Section VIII, Division of the ASME Code, allowable stresses shall be determined in accordance with the procedures outlined in Subsection C and Appendix P of that section Where it can be shown that the values of allowable stress listed for a particular material in one product form (because of similar chemistry, mechanical properties, heat treatment, and so forth) are applicable to the same material in an unlisted product form, the listed values of allowable stress may be used Ordering Information 5.1 Orders for products under this specification shall include the following information as applicable If a manufacturer’s standardized product is being ordered, include all data needed by the manufacturer to define the product 5.1.1 Make 5.1.2 Model (simplex or duplex) 5.1.3 Port size 5.1.4 Port connections 5.1.5 Maximum allowable pressure/temperature rating 5.1.6 Body and cover material

test in accordance with the requirements prescribed in paragraph UG-101 of Section VIII of the ASME Code If burst-type tests as outlined in paragraph UG-101(m) are used, it is not necessary to rupture the component In this case, the value of B to be used in determining the MAWP shall be the maximum pressure to which the component was subjected without rupture Safety of personnel shall be given serious consideration when conducting proof tests Components that have been subjected to a proof test shall not be offered for sale 5.2 If a product is to be specified by performance criteria rather than model description, then the following should be specified: 5.2.1 Maximum allowable clean pressure loss at a given flow capacity of a given liquid at a given velocity 5.2.2 Temperature and
